Пошаговое объяснение:

$3\frac{5}{6}:2\frac{5}{9} =4\frac{1}{8} :x\\ \\ 3\frac{5}{6}x=4\frac{1}{8} *2\frac{5}{9}\\ \\ 3\frac{5}{6}x=\frac{33}{8} *\frac{23}{9} \\ \\ 3\frac{5}{6} x= \frac{253}{24} \\ \\ x=\frac{253}{24} :3\frac{5}{6}\\ \\ x=\frac{253}{24} *\frac{6}{23} \\ \\ x= \frac{11}{4} \\ \\ x=2\frac{3}{4}$

$\frac{3,8}{0,1x+3} =\frac{10}{11} \\ \\ 10(0,1x+3)=11*3,8\\ x+30=41,8\\ x=41,8-30\\ x=11,8$
